WebThe formula for the area of a sector is (angle / 360) x π x radius2. The figure below illustrates the measurement: As you can easily see, it is quite similar to that of a circle, but modified to account for the fact that a sector is just a part of a circle. Example: find the area of a circle. Task 1: Given the radius of a circle, find its area. … WebThe area of a sector in terms of L can be obtained by multiplying the total area πr2 by the ratio of L to the total perimeter 2 πr . Another approach is to consider this area as the result of the following integral: Converting the central angle into degrees gives [3] Perimeter [ edit]
WebThe sector area is recalculated as you drag. What the formulae are doing is taking the area of the whole circle, and then taking a fraction of that depending on what fraction of the circle the sector fills. So for example, if the central angle was 90°, then the sector would have an area equal to one quarter of the whole circle. WebJan 11, 2024 · Formula to find area of a sector This formula helps you find the area, A, of the sector if you know the central angle in degrees, n°, and the radius, r, of the circle: A=\frac …
WebArea of a sector formula: Area of a sector = θ 360 ×πr2 360θ × πr2 θ = angle of the sector r r = radius of the circle In order to solve problems involving the area of a sector you should … WebA sector is the area of a circle which has been enclosed by two radii and the arc between them. A sector is not to be confused with a segment of a circle. A segment is when the area enclosed by the chord of a circle and the arc of the chord.
